Getting to know your Fitbit Charge 2
This section tells you how best to wear, navigate, and charge your tracker. If you
bought an accessory wristband, you’ll also find instructions for taking off the original
band and putting on a different one.
Wrist placement
Review these tips to make sure you’re wearing your tracker for optimal results.
All-day wear and exercise
For all-day wear when you’re not exercising, your Charge 2 should usually rest a
finger’s width below your wrist bone and lay flat, as you would normally wear a
watch.
For optimized heart rate tracking keep these tips in mind:
1.! Experiment with wearing the tracker higher on your wrist during exercise.
Because blood flow in your arm increases the farther up you go, moving the
tracker up a couple inches can improve the heart rate signal. Also, many
exercises such as bike riding or weight lifting cause you to bend your wrist
frequently, which is more likely to interfere with the heart rate signal if the
tracker is lower on your wrist.
